you have a reason for not resigning, all he has left is 1 pawn and his king cannot leave the queenside because of the adjacent passed pawns.. the best black could hope even after losing the queen is a draw..
(that's only my low rated opinion, stronger players could give you a better one
)
How many times have you been in a totally lost position and made a comeback (in the form of a win or draw)?
What circumstances was it under (casual, rated OTB, rated online, etc)?
Who did you play (approximate rating/skill level)?
How has this changed your opinion on resigning a game?
This was one of my games where I messed up terribly and still won.
